Abstract:
The present invention relates to a process for the manufacture of coatings by applying ionizing radiation to a composition which contains olefinically unsaturated polymeric materials having urethane groups and has been applied to a substrate. The polymeric materials, which may be used in combination with olefinically unsaturated monomeric compounds and conventional additives, contain, in the same molecule, at least two units of the general formula
AND/OR
WHERE R is hydrogen or methyl.

Abstract:
A process for the manufacture of curable unsaturated polyester molding compositions. To a mixture of A. AT LEAST ONE UNSATURATED POLYESTER, B. AT LEAST ONE COPOLYMERIZABLE OLEFINICALLY UNSATURATED COMPOUND, C. AN ALKALINE EARTH METAL OXIDE AND/OR HYDROXIDE, D. AT LEAST ONE INHIBITOR AND, OPTIONALLY, E. CONVENTIONAL FILLERS, REINFORCING AGENTS, INERT SOLVENTS, POLYMERIZATION ACCELERATORS AND/OR OTHER AUXILIARIES CONVENTIONALLY USED IN THE PROCESSING OF POLYESTER MOLDING COMPOSITIONS, THERE IS ADDED FROM 0.005 TO 1% BY WEIGHT, BASED ON UNSATURATED POLYESTER RESIN (A) PLUS (B), OR AT LEAST ONE COMPOUND OF THE GENERAL FORMULA
Abstract:
Wood material surface coating, particularly for chipboard, consisting of a paper impregnated with an aminoplast or phenoplast resin and coated on the upper side with a curable polyester resin consisting of non-crystalline and crystalline portions.
Abstract:
Curable unsaturated quick-thickening polyester resin molding compositions for the manufacture of prepregs, compression molding materials and the like are obtained by adding special onium salts as thickening accelerators to unsaturated polyester resins.
Abstract:
Curable unsaturated polyester molding materials which give high viscosities without the flow properties of the molding materials being adversely affected during processing are manufactured from a) an unsaturated polyester mixture consisting of an amorphous polyester and a crystalline polyester, b) at least one copolymerizable olefinic compound,c) an alkaline earth metal oxide and/or hydroxide, d) at least one inhibitor and e) conventional assistants and additives.
